Getting a Good Night’s Sleep


A sleep evaluation begins with a detailed sleep and wakefulness history and exam by our expertly trained sleep specialists, or Board Certified Sleep Physician.  A patient may then be asked to monitor and record his or her sleep and nap schedules by keeping a diary.  This may be followed, in some cases by an overnight sleep study (polysomnogram) to observe, evaluate, and record nighttime sleep.  Daytime wakefulness may be evaluated with a Multiple Sleep Latency Test (MSLT), a reproducible measure of sleepiness.  The ability to stay awake may be evaluated with a Maintenance of Wakefulness test (MWT).  With this information, a definitive diagnosis may be reached and an appropriate treatment plan developed.  Out treatment philosophy to the management of sleep disorders relies on the following approach:

 

  • Patient education
  • Behavioral modification
  • Judicious use of pharmotherapy
  • Specific interventions such as CPAP, BiPAP or a dental device for sleep apnea
  • Light therapy for circadian rhythm disorders
  • Pulmonary, and/or otolaryngological (ENT), consultation when indicated

 

 

The Sleep Laboratory


Our sleep laboratory is a 6-bed facility which has been designed for the purpose of studying sleep disorders.  Because the study of such disorders requires getting people to go to sleep, our sleep lab is designed to be a comfortable place to sleep with the look and feel of a small hotel suite without compromising the mission of being a world-class scientific facility.


The following studies are performed in the sleep laboratory:


Overnight Polysomnogram: a sleep evaluation that is used to diagnose a number of sleep disorders.  It is the sleep specialist’s baseline study to see how you sleep.  It is a completely painless, non-invasive test that monitors brain waves, the levels of sleep that one attains, leg movements, eye movements, and respirations.


Overnight Polysomnogram with CPAP Titration: CPAP is a device used to treat obstructive sleep apnea. CPAP is an acronym for Continuous Positive Airway Pressure and if you are diagnosed with obstructive sleep apnea, your physician may recommend treatment with CPAP. The overnight Polysomnogram with CPAP titration study is a study similar to the Overnight Polysomnogram, with the exception that you will be fitted for a CPAP interface connected to a CPAP machine. The CPAP machine generates a cushion of air in the back of your throat that keeps your airway open, thusly eliminating any sleep apneic events. The technologists will gradually increase or decrease the pressure throughout the night, whichever treats your apnea best.

Multiple Sleep Latency Test (MSLT): The MSLT is a sleep disorder diagnostic tool used to distinguish between physical tiredness and true excessive daytime sleepiness, or to assess whether treatments for breathing disorders are working. Its main purpose is to serve as an objective measure of sleepiness. The test is conducted during the day and consists of four or five 20-minute nap opportunities that are scheduled two hours apart. The test is often performed after an overnight sleep study. During the test, data such as the patient's brain waves, muscle activity, and eye movements are monitored and recorded.


Maintenance of Wakefulness Test (MWT): The MWT is a diagnostic test to identify one's ability, or inability to stay awake in individuals who have excessive daytime sleepiness. It is a test meant to objectively measure one's ability to stay awake, which can infer how sleepy you are. The test may also be used to assess your response to treatment of various sleep disorders, including sleep apnea or narcolepsy. The test is conducted during the day and consists of four 40-minute opportunities to stay awake that are scheduled two hours apart. The test is often performed after an overnight sleep study. During the test, data such as the patient's brain waves, muscle activity, and eye movements are monitored and recorded.

What is Sleep Apnea?

Sleep apnea (AP-ne-ah) is a common disorder in which you have one or more pauses in breathing or shallow breaths while you sleep. Breathing pauses can last from a few seconds to minutes. They often occur 5 to 30 times or more an hour. Typically, normal breathing then starts again, sometimes with a loud snort or choking sound. Sleep apnea usually is a chronic (ongoing) condition that disrupts your sleep. You often move out of deep sleep and into light sleep when your breathing pauses or becomes shallow.

What is CPAP (Continuous Positive Airway Pressure)?

CPAP, or continuous positive airway pressure, is a treatment that uses mild air pressure to keep your airways open. CPAP typically is used for people who have breathing problems, such as sleep apnea.
